Hi Dan --

Does this handle DHCP as well?  If so, can you provide a pointer to more
information?

Thanks,

P.S. With the patch I posted yesterday, the admin doesn't have to modify
shell scripts for vif-nat and network-nat though admittedly the scripts
modify them directly which is probably OK if dom0 is not otherwise used
as a dhcp server.
